Özet

This paper presents experimental vibration analysis of the induction motor by applying a short-time Fourier transform (STFT), which is one of the spectral analysis methods. Vibration data of a small-sized induction motor were obtained with a laser Doppler vibrometer (LDV). Experimental setup was assembled in order to register motor vibrations. Data-acquisition system was employed to register the vibrations of the induction motor. LDV measurement data was collected when the induction motor was operating at various speeds under no-load condition. The obtained data were analyzed by means of short-time Fourier transform method. Finally, the results of analysis were interpreted to demonstrate certain vibrational behavior of the motor.
